Anchoring device for fastening equipment to the foundation

 

(57) Abstract:

The inventive anchoring device comprises a rod with nut, sliding sleeve and the thrust tube. The lower part of the rod is made with two cones, which are located at a distance from each other and facing each other with smaller bases. Between the cones installed spring. Sleeve cover cones. Pipe rested in the greater base of the upper cone. 3 Il.

The invention relates to the field of construction and can be used for mounting various equipment to the bearing surface of the structures subjected to both static and dynamic effects, for example for attaching the vibrator to the foundations of the turbines with their dynamic tests.

Known anchoring device for fastening equipment to the supporting elements of the structure, consisting of a steel rod with threads on one side and a tapered shank on the other, which is installed in a hole formed in the finished concrete or reinforced concrete element construction, and is secured therein by cement mortar.

A disadvantage of this device is the length of the mounting anchor is escueta under the influence of alternating dynamic loads, for example, when the vibrators during dynamic testing of structures, which lengthens the process of construction and reduces the accuracy of the test results.

Famous anchor for fastening elements to the base, taken as a prototype. This device consists of a rod with the expansion part at the lower end and sliding cheeks, contractible elastic ring. In a prepared cylindrical hole of the base install anchor and load vertical force by screwing the shank of the nut, resulting cheeks apart, i.e. rasklinivanie in the hole.

The disadvantage of this anchor is that it takes only a tensile load and not takes the load of the opposite direction (compression).

The aim of the invention is to increase the strength and reliability of fastening equipment to the building structure with alternating dynamic loads, reducing the time of installation of the equipment.

The aim is achieved in that the anchoring device comprising a rod with a nut at one end and tapering toward the nut cone at the other end, sliding poluchulki with the toothed surface is tym primary and freely mounted on the rod, additional polutonami covering additional cone, and a spring disposed between the cone and the tube is rested more additional cone.

The proposed anchor the device in comparison with the known able to perceive large static and alternating dynamic loads in tension and compression, for example, when it is used for mounting vibrators necessary to conduct dynamic tests such important structures, which are the foundations for the turbines of great power.

The hallmark of the claimed device is an introduction to the composition of the new element - additional inverted cone with sliding polutonami serrated surface, which in combination with the lower main cone allows us to perceive the device as tensile and compressive effort of static and dynamic nature.

By introducing additional inverted cone increases reliability, rigidity and strength of the work anchorage devices.

In Fig. 1 shows the structure of the anchoring device to a load; Fig. 2 - the same, after application of the load; Fig serrated surface, spring (4), resistant pipe 5, the nut 6, the washer 7, the rings 8, pin 9, the clamping spring rings 10 and the centering washer 11 with vertical grooves 12.

The terminal 1 is in the upper part of the thread for screwing the nuts 6.

Of the two cones 2 lower (main) welded to the rod 1, the top (optional) freely mounted on it.

Poluchulki 3 serrated surface, attached to the 2 cones, tighten the spring rings 10 and kept them in the original position by the rings 8 and pins 9. Sliding poluchulki have 3 on the outer surface of the teeth that are cut into the concrete well construction designs when installed in her anchors, and the grooves for clamping spring rings 10 and vertical grooves 13 for the passage of liquid epoxy composition when filling it after mounting the anchoring device in the well of the building structure (in the case of the use of anchor devices in structures subjected to large alternating dynamic loads), as well as to provide a lighter of the cutting teeth polovchak 3 in the concrete when rasklinivanie them by reducing the perimeter of teeth.

Resistant pipe 5 is designed to transfer forces on the top add the liquid composition to the surface of the rod 1.

Spring 4 serves to hold the upper Assembly from contact with the bottom in the original position.

In the upper part of the anchoring device on the thrust tube 5 is wearing a centering washer 11 with vertical grooves 12, intended to convey the concrete 15 building construction horizontal alternating dynamic loads. Vertical grooves 12 in the center of the washer 11 serve for the passage of the liquid composition in the case fills her hole 16.

Installation of the anchoring device is as follows.

The rod 1 is welded to the lower (main) cone 2 consistently put the details and components of the lower Assembly: sliding poluchulki 3 serrated surface, the ring 8, and the grooves of polovchak inserted coupling snap ring 10. Then in the side holes of the cone 2 is driven pins 9, the retaining ring 8 and the sliding poluchulki 3 with a spring ring 10 on the cone 2.

Next on the rod 1 put the springs 4 and the upper Assembly consisting of the same components as the bottom, cone bottom. Then on the rod 1 put pressure pipe 5, the centering washer 11 and the washer 7, after which the rod nut 6 is screwed to touch her on the washer 7.

Then p is TES anchor the device to the stop rod 1 at its bottom. Then screw on the rod 1 nut 6.

When tightening nuts 6 (i.e., loading of the rod 1 vertical force), the following occurs. Nut 6 presses through the washer 7 and the centering washer 11 on the thrust tube 5, creating a longitudinal force directed down the well, which presses on the top (optional) 2 cone. Under the action of this force, the upper cone is moved down, sliding along the rod 1, pushes the remaining on the upper sliding poluchulki 3, resulting in the well 16 is created disjoining force, shown in Fig. 2 by the arrows. Under the influence of disjoining force poluchulki 3 cut its serrated surface in concrete 15 building construction. At the same time when tightening the nut 6 terminal 1 under the action of a force directed upwards, rises, pulling the lower (main) cone 2, which pushes the lower poluchulki 3, the last of its toothed surface cut into the concrete building structure.

When the spring 4, to contract, does not preclude convergence to each other the lower (main) and the top (optional) cones.

After complete cutting teeth polovchak 3 in the concrete stop screwing the nut 6, when Etna Fig. 2. Thanks to the cutting teeth of polovchak 3 in concrete construction design provides durable grip anchors to the concrete.

After installation of the equipment on the Foundation of a building by the occurrence of alternating dynamic loads anchor device operates as follows.

If there is a vertical force directed upwards, the lower Assembly, sensing that power and transmitting it to the Foundation; if there is a vertical force directed downwards, similarly works the upper Assembly.

Occur when the equipment is operated horizontal alternating dynamic loads are perceived by the washer 11, the centering anchor the device in the borehole 16.

For the perception of large alternating dynamic loads bore 16 after mounting it and tightening the anchoring device is filled polymer composition, such as epoxy glue.

The use of the invention allows to increase the reliability of the obtained results in dynamic testing of structures and structural design.

The invention can be used in both new construction predpriyatiya often moved from place to place, for example, when the change process.

ANCHORING DEVICE FOR FASTENING EQUIPMENT TO the FOUNDATION including a rod with a nut at one end and tapering toward the nut cone at the other end, sliding poluchulki serrated surface, covering the cone, and freely mounted on the thrust rod pipe, characterized in that, to improve reliability of the device it is provided with an additional cone, reverse the primary and freely mounted on the rod, additional polutonami covering additional cone, and a spring disposed between the cone and the tube is rested more additional cone.
